Pe it known that l, CHARLES F. Deurne, a citizen of the United States, residing at Philadelphia, 'county of Philadelphia, State of Pennsylvania, have invented a certain new and useful improvement in Cooling Systems, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a partof this specification. ,t

h/ly vention relates/t0 cooling systems and a special object of my improvements is to provide ani improved means -for automatically regulating the cooling of autoll secure this object inthe device illustrated in the accompanying drawings in which;

Figure l is a front elevation of an automobile radiator partly broken away to show the interior construction thereof and adi jacent parts embodying my invention.

lj same.

1 showing the adjustable pawl by-which the- Figure 3 is a detail sectionalview of a portion of said radiator and attached parts to an enlarged scale.

Figure 4 is a viewsimilar to Fig. 3 show ing the parts in a different position.

Figure 5 is a vertical sectional view to /a somewhat enlarged scale of the radiator and adjacent parts shown in Fig. 1 and also showing the fanL in its relative position. A

Figure 6 is a detail sectional plan view blinds may be held in an approximately closed position. v

a is the frame, creasing, of the radiator. bf indicates blind slats of the 'kind commonly called Venetian blinds. These slats are pivoted eccentr'cally as shown and have their pivotal axesvertical. The pivotsare' indicated by the reference 'character b2 and consists of vertical Vstationary pintles er.-Y tendngupward into apertures in the lower end of the blinds. not permit the accumulationof water at the joints which might prevent their operation. e is a rod pivotally attached to each of the blinds b' atthe same distance eccentrically from its pivot.l By moving the rod ein the direction of its length all the ^blinds b are This construction does.-

simultaneously turned about their pivots` .152. f (Fig. 2) is a tension spring acting to draw'the rod toward the closed position of the blinds b. d is the core, or cooling surface, of the radiator.

c is the fan by which the cooling current of air isactuated to cause it to pass thru and over the cooling surface al Uf course the motion of the vehicle will also cause a current of the air to passthru and over said cooling surface.

h3 is the blade of a vane having a considerable surface and interposed in the path of the current of air' passing thru and over the cooling surface 0l. This blade is pivoted at k2' on a vertical ivot and extends to the other side of said plvot in an arm h. g is a connecting rod pivoted at one end to-the i in Fig. 4.-, to hold the blindsfb in their approximately closed positionor to be withdrawn therefrom, as shown in Fig. 3, so that the blinds are free to move about their pivotsv b2. j is a thermostatic strip having its outer end connected by a rod jz to the in the line of travel of the linger b3, as shown stop z'. yThe strip j is fastened to the casing of the radiator, or in some position so that it'will be subjected to the heat of the radiator.

The construction and arrangement of the parts just described is such that when the radiatorv is cold the stop i will be interposed in the travel of the finger b3 and hold the blinds Z) in their approximately closedV position. When the temperature of the radiator rises the strip y' will be moved to draw the stopt outfof line of travel of the linger b3 so as to permit of the turning of the blinds about their pivots. The stop itself may be made of thermostatic metal and so located as to be subjected to the temperature of the radiator if desired.

The operation of the above described` device is as follows: l

When the radiator is cold and the engine started up the blinds bare h eld nearly closed rises and causes the thermostat to withdraw the stop i from the line Yo travel of thenger b3. The current of air, or dilerence of airpressure., caused by the lan c or the motion of the vehicle acts upon the slats I) to turn them from their approximately closed position and the airpassing thru between said slats'and thru the cooling surface strikes against the vane blade k3 turning the vane about its pivot 71.2 and by means of therod g actuating the blinds b to their furthest open position and holding them in this position as long as the current ,of air is passing.

When the engine and vehicle stop the current and pressure of air no longer` acts upon the blinds and vane and the spring draws the slats towardtheir closed position. lf the engine and parts remain at rest until the radiator cools down the lslats are held in this position by the stop i but if the engine is started up' before the radiator cools down the slats are again immediately automatically opened as above described.

' By turning the'screw k the stop i may be adjusted in length so as to limit the opening movement of the blinds to the position desired. f

c gz-is a set screw for limiting the open travel of the blinds under all conditions, and is a similar setscrew for preventing the complete closure of the blinds.

What'l claim is:

1L In an apparatus of the kind described, the combination of a fan', adapted to be driven by the engine at a speed proportional tc that of the engine, a radiator, said fan to-that of the engine, a radiator, said fanbeing adapted to propel a current ot 'air over the cooling surface of said radiator, a damper arrangement adapted to control the area of passage for the cooling air, ai

pivoted vane located in the current of air produced by said-fan upon the same side of said damper as said fan, said Vanebein connected with said damper so that it sha l actuate the same to -vary the area of passage for the cooling air.,

2. In an apparatus ofthe kind described,- the combination of a fan, adapted to be driven by the engine at a speed proportional being adapted to ropel a current of air over the cooling sur ace of said radiator, a damper arrangement adapted to control the area of passage for the cooling air, a pivoted Vane located in the current of 'air produced -by`- said fan' upon the same side of said damper as said fan, said vane being con,- nected with said damper so that it shall actuate the same to vary the area of passa e for the cooling air, means for automatically actuating said damper towards its closed position and an adjustable stop to limit th closing motion of said damper. f

mendaci said damper being adapted to be actuated by Y the presure of the air, means for restraining the movement of said damper, said restraining means being adaptedto be automatically withdrawn from its operative position.

4. 'lhe combination with a radiator having a cooling surface, a damper adapted to regulate the area of passage for the cooling air, said damper being adapted to be actuated by the pressure of the air, means for restraining themovement of said damper, said restraining means being adapted to` be automatically withdrawn from its operative position, by heat imparted from said radiator.

5. rlhe combination with a radiator having a cooling surface, a damper for adjusting the area of passage for the cooling air, said damper being adapted to be forced to its open position by an air current, a spring actuating said damper towards its closed position, a vane interposed in the line of .a cooling surface, a damper for adjusting the area of passage for the cooling air, said damper being adapted to be forced' to its open position by an air current, a spring ,actuating said damper towardsrits closed position, a vane interposed in the line of travel of the cooling air, said vane being connected with said damper to open the same and a detent adapted to hold said damper in :a position slightly removed from its closed position; means for adjusting said detent for the purpose described. l

7. The combination with aradiator having a cooling surface, a damper for adjusting the area of passage for the cooling air,
